Abstract

The transformer comprises a magnetic core, a primary side assembly and a secondary side assembly, the primary side assembly comprises a primary side winding and a primary side supporting piece, the primary side winding is wound on the primary side supporting piece, and the primary side winding is made of a copper foil material; and the secondary side assembly comprises a secondary side winding and a secondary side supporting piece, the secondary side winding is wound on the secondary side supporting piece, and the secondary side assembly is installed on the outer side of the primary side assembly. According to the transformer with the structure, the primary winding is formed by winding the copper foil, so that the equivalent excitation inductance of the transformer is increased, and the equivalent leakage inductance of each winding is reduced. Leakage inductance values of primary and secondary sides of the transformer are reduced, and the output power of the transformer is further improved.

Description

technical field [0001] The invention relates to the technical field of transformer structures, in particular to a transformer and a high-voltage generator. Background technique [0002] High-voltage generators are the core components of medical X-ray machines, CT, vacuum welding power sources, high-voltage electrostatic precipitators and other devices, and are widely used. Among them, the high-frequency transformer is an extremely critical component. Due to the large variation of the primary side and the secondary side of the high-frequency transformer, the distributed capacitance and leakage inductance of the transformer winding will increase sharply, resulting in the phase and The problem of poor consistency between phases. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved by the present invention is that the transformer in the prior art has a large change ratio between the primary side and the secondary side of the high-frequency transform...
